PORSCHE YARN CARRIER Filed May 17, 1955 lnvznfor f'l'aik/a 5 11 1441: f A fr- 15 AMP United States Patent CL YARN CARRIER ErichPorsche, Lindau-Zech, Germany, assignor to Jottka MetallwarentabrikEdgar G. Schob, Baden, Germany, a German firm Application May 17, 1955,Serial No. 509,063 Claims priority, application Germany May 18, 1954 2Claims. (Cl. 66-126) The present invention relates to improvements inyarn carriers, and more particularly to yarn carriers for fullfashionedhosiery knitting machines wherein the thread is finally payed outthrough a thin thread-guiding member which extends intermediate thesinkers and is slightly inclined toward the rear, terminating slightlyabove the upper edge of the distributing bar.

Prior to this invention such thin thread-guiding member usuallyconsisted of a fine-gauge tube which was mounted on the lower end of ayarn carrier or yarn carrier finger and through which the thread waspayed out to the sinkers.

In actual practice, these thin thread-guiding tubes especially forfine-gauge machines are very difficult to produce and requireconsiderable space laterally since the walls thereof may not be madebelow a certain strength, as otherwise the thread might be cut by theedge of the thread opening. This danger prevails especially if thread orfully synthetic yarn is used which may be knitted on machines of thistype up to a weight of 5 denier. Owing to the small inner diameter ofthese tubes, they are easily clogged, and the removal of suchobstruction requires a considerable time as well as frequent replacingof the tube.

It is an object of the present invention to eliminate thesedisadvantages by providing the yarn carrier with a needle having an eyeat its free end similar to a sewing needle.

Another object of the present invention is thus to provide a threadguide which is much more easily threaded than a thread-guiding tube,through which it is very difficult to pass the thread, especially ifresinous matter or lint has settled therein.

A further object of the present invention is therefore to provide athread guide which does not exert an uncontrollable binding or brakingaction upon the thread which occurs very frequently when using thin, andeasily clogged thread-guiding tubes, resulting in uneven tension of thethread in the stocking.

Another object of the present invention is also to obtain a thread guidewhich is resilient and will deflect toward the side if it should engagewith a sinker, or any part thereof. If the free end of such athread-guiding needle according to the present inverition is alsoprovided with a sharp point, it will be practically impossible for itever to damage a sinker.

Another material advantage of the thread-guiding needle according to thepresent invention is that, owing to its smaller diameter as comparedwith a thread-guiding tube, it may be adjusted to a single gauge,whereas the latter, because of its larger diameter, will always overlaptwo gauges or distributing bars. Thus,-it is another important featureof the invention that it permits the use of two thread-guiding needlesona single yarn carrier, for example, when the Work requires two threadsto be used simultaneously.

Still another advantage of the thread-guiding needle is that it can bemade of a better steel and can be more easily and more highly polishedthan the customary thread-guiding tube.

Further objects, features, and advantages of the present invention willbe apparent from the following detailed description thereof, as well asfrom the accompanying drawings, in which Fig. 1 shows a customary yarncarrier with a threadcarrying tube mounted thereon in its positionrelative to the sinkers;

Fig. 2 shows a side view of the yarn carrier according to the inventionwith a thread-guiding needle at its free end;

while Fig. 4 shows a front view of a yarn carrier with two needlesaccording to the invention mounted thereon.

Referring to the drawings, Fig. 1 shows the customary yarn carrier witha thread-carrying tube 2 mounted on its lower end so as to be in aposition intermediate two sinkers 3 above the upper edge of distributorbar 4.

The relative thickness of the tube 2 to the bars 3 and 4 as shown in thedrawing substantially corresponds to the conditions prevailing in actualpractice. It is evident from this drawing that the tube 2 will besubject to considerable stresses and difliculties if used with smallgauges.

Fig. 2 shows a yarn carrier finger 5 with a threadguiding needle 6mounted on its free end. The thread 7 runs through the lead eye 8 andthen through the eye 9 on the yarn carrier finger 5 to the thread eye 10in the needle 6.

A preferred embodiment of the thread-guiding needle 6 is shown, forexample, in Fig. 3. The needle shaft 7 is thickened so as to permit theneedle to be more easily secured to the free end of the yarn carrierfinger 5. Its free end is provided with a thread eye 10, and the needlepreferably terminates in a sharp point 11. As illustrated in Fig. 2, theend of the thread 7 preferably leads forwardly along the needle 6 andthen passes through the needle eye 10-toward the rear.

Fig. 4 illustrates the application of the invention to a yarn carrier 12which is provided with two thread-guiding needles 13 and 14, which arebent relative to each other above the sinkers at a point 15' and 16,respectively, so that, when seen from the front, the lower ends thereofare disposed at a right angle to the sinkers and may be so close to eachother as to permit both needles to pass safely between two adjacentsinkers 3, that is, each needle within one division or gauge 3-4. It isevident from a comparison of Figs. 1 and 4 that a thread-guiding needlemay be made of considerably thinner diameter than a thread-guiding tubeas previously used, thus even permitting two needles to be used withinthe same area where only one tube could be used, apart from itsadvantage over such a tube of being more easily threaded and not liableto collect lint or resinous matter which easily clogged the passage andopening of a tube and exerted a binding or braking action upon thethread which might affect the quality of the hosiery knitted on themachine.

Although my invention has been illustrated and described with referenceto the preferred embodiments thereof I wish to have it understood thatit is in no way limited to the details of such embodiments or to thespecific examples described, but is capable of numerous modificationswithin the scope of the appended claims.
